A pool of urine constantly remains in the bladder that cannot empty properly. The obstruction prevents the normal emptying of the bladder. This occurs when there is an obstruction to the outflow of urine. The other causes listed below are less common Overflow incontinence Most cases of urinary incontinence are due to the above causes. Some people have a combination of stress and urge incontinence. Examples are Parkinson's disease, multiple sclerosis (MS), spinal cord injury and after a stroke. Some people with certain neurological disorders may experience urge incontinence. ![]() See the separate leaflet called Urge Incontinence for more details.ĭiseases or medical conditions affecting the nervous system are called neurological disorders. Sometimes urge incontinence can occur because of problems with the nervous system (the brain, spinal cord and other nerves in the body). It seems that the bladder muscle gives wrong messages to the brain and the bladder may feel fuller than it actually is. This is called idiopathic urge incontinence. In most cases, the cause of urge incontinence is not known. The bladder muscle contracts too early and the normal control is reduced. Sometimes urine leaks before you have time to get to the toilet. This is the second most common cause of urinary incontinence. Urge incontinence (unstable or overactive bladder) This includes surgical removal of the prostate (prostatectomy), and radiotherapy. Stress incontinence can occur in men who have had some treatments for prostate cancer. See the separate leaflet called Stress Incontinence for more details. Stress incontinence is common in women who have had several children, in obese people and with increasing age. Stress incontinence may also be a side effect of pregnancy, as pelvic floor muscles are often weakened by childbirth. Sometimes much larger volumes of urine are accidentally passed. In these situations there is a sudden extra pressure (stress) inside the tummy (abdomen) and on the bladder. ![]() Urine tends to leak most when you cough, laugh, sneeze or exercise (such as when you jump or run). This is usually caused by weak pelvic floor muscles. It occurs when the pressure in the bladder becomes too great for the bladder outlet to withstand. This is the most common type of urinary incontinence. There are several different types of urinary incontinence: What are the causes of urinary incontinence? Female urinary system This is unfortunate, as many cases can be successfully treated or significantly improved. Some people wrongly think that incontinence is a normal part of ageing or that it cannot be treated. Many people do not tell their doctor about their incontinence, due to embarrassment. It is likely that the true number of people affected is much higher. ![]() However, as many as 1 in 5 women over the age of 40 have some degree of urinary incontinence. It is estimated that about three million people in the UK are regularly incontinent. It can occur at any age but it is more likely to develop as you get older. Urinary incontinence is common, especially in women. These tell you how full your bladder is and tell the correct muscles to contract or relax at the right time. When you go to the toilet to pass urine, the bladder muscle squeezes (contracts) and the urethra and pelvic floor muscles relax to allow the urine to flow out.Ĭomplex nerve messages are sent between the brain, the bladder and the pelvic floor muscles. When a certain volume of urine is in the bladder, you become aware that the bladder is getting full. This is helped by the muscles below the bladder that surround and support the urethra (the pelvic floor muscles). The outlet for urine (the urethra) is normally kept closed. It expands like a balloon as it fills with urine. The bladder is made of muscle and stores the urine.
